Abstract: A rewrite determining unit of a hard disk apparatus acquires a servo signal that includes an offtrack amount corresponding to each servo frame from a position information memory, and determines whether a write fault has occurred based on the servo signal. If a write fault has occurred, the rewrite determining unit determines a rewrite sector count, and a write controller controls a hard disk controller so that rewriting is performed to correspond to the rewrite sector count determined by the rewrite determining unit.

Abstract: A heater for changing a projection distance protrusion value by thermal expansion accompanying electric-power-distributed heating is embedded in a head having a reading element and a recording element. A clearance control information measurement unit measures and saves, at desired correction timing, clearance control information including a clearance required for controlling the clearance between the reading element and the recording medium, heater projection sensitivity protrusion sensitivity, projection distance protrusion value transition time, recording current projection distance protrusion value, and a temperature correction coefficient. The clearance control unit varies the electric power distributed to the heater and changes the projection distance protrusion value of the head, thereby controlling the clearance to a target clearance upon reproduction and recording.

Abstract: While there are contact joining and capacitance type switches for detecting an operation of a door handle, a problem that is to be solved by the invention is to solve problems of contact failure due to aging and a malfunction triggered by rain drops. According to the invention, a piezoelectric sensor (4) has such flexibility as to be annexed to a door handle (3), whereby a minute displacement of the door handle (3) can be detected with high sensitivity. Consequently, a sufficient signal output can be obtained only through a simple touch to the door handle (3), whereby a touch or contact to the door handle (3) can be detected. In addition, since electrodes are not exposed to the outside, the piezoelectric sensor (4) is made difficult to be affected by disturbance, and dust, rain, snow and the like which come to adhere thereto. Furthermore, since the piezoelectric sensor (4) can be deformed with suppleness, there are imposed few limiting conditions on a setting place and a space where to dispose the piezoelectric sensor (4) is diminished.

Abstract: Disclosed is a servo gain compensating method for compensating a servo gain when in a seek operation and in a positioning process in an information storage device. The servo gain compensating method and a device thereof make compensation to a precise servo gain even when a temperature changes abruptly. The information storage device includes a head for reading information from a storage medium, an actuator for moving the head, a control circuit for calculating a drive quantity compensated by the servo gain value from positional information read by the head, and a driving circuit for driving the actuator on the basis of the drive quantity. The servo gain compensating method includes a step of periodically measuring a temperature of the information storage device through a temperature detecting element for measuring the temperature of the device, a step of judging whether or not a difference between the measured temperature and the temperature measured last time is over a fixed value, a first step of obtaining, if the difference is not over the fixed value, a servo gain value referring to a first table of a first servo gain characteristic, and a second step of obtaining, if the difference is over the fixed value, a servo gain value referring to a second table of a second servo gain characteristic. In the second step, a calibration seek may be executed.
